  1. Prior Appropriation WR

  2. Envision’s Water Right Input data Spatial Data a. OWRD Point of Use (POU) layer b. OWRD Point of Diversion (POD) layer c. WW2100 IDU layer d. WW2100 Stream layer Text file (columns and Rows) a. POD table i. WR ID number ii. Coordinates iii. Place of Use POUID iv. PODID v. Diversion rate (m3/sec) vi. Diversion type (ground, surface, etc) vii. Use codes (Muni., irrigation, etc) viii. Priority date (>1839) iv. Relates to Envision Reach x. Begin and End dates for diversions a. POU table i. POUID ii. IDU_INDEX Relates to Envision IDUs iii. Area of intersection m2

  3. Envision’s water right to do list Surface water How to represent Minimum Flows throughout the stream reach network a. Control Points on the mainstem (reservoir operation USACE) b. OWRD In stream Water Rights (only some reaches) c. Total Maximum Daily Load (TMDL) (relationship between discharge and temperature) Contracted Water Rights stored in reservoirs (USACE) a. Priority dates? b. Points of Use? Ground water (under development)

  4. Flow Model (daily time step loop) HRUs (comprised of stream reaches) Stream Reach Discharge (SRD)m3/day Water Right loop ( begin with Senior WR ) IDU loop ( A Place Of Use can have multiple IDUs) Calculate Available Reach Discharge (ARD) m3/day. ARD = SRD – minFlow – ISU - OSU Aggregate SRD to HRU Is ARD ≥ 0? IDU WR Use yes no Consider next WR Is the Use an “In Stream” Use (ISU) Consider next junior WR no yes no Have all WR been considered yes Add Demand rate to “Out Stream” Use (OSU) IDU Water Demand (m3/day) Add Demand rate to ISU Subtract Out Stream Use from Stream Reach Discharge SRD = SRD - OSU Have all IDUs been considered? yes no Consider next IDU
